Observations on Some of the Basic Concepts of Electrocardiography

Abstract

Most electrocardiographers do not appear to understand that certain concepts, widely accepted and regarded as basic, are derived from, simplifications of a type more familiar to engineers than to physicians. Consequently beginners are taught technics, the validity of which depends on the applicability of these simplifications to the conditions encountered in the body. An attempt has been made to inquire into a few of these matters as simply as possible.
